_q_uuidFromHex()

static Q_NEVER_INLINE QUuid _q_uuidFromHex ( const char *  src )

static

Parses the string representation of a UUID (with optional surrounding "{}") by reading at most MaxStringUuidLength (38) characters from src, which may be \nullptr. Stops at the first invalid character (which includes a premature NUL).

Returns the successfully parsed QUuid, or a null QUuid in case of failure.
